Step 2: Check the PROTOCOL File
Step 2: Check the PROTOCOL File
If the PROTOCOL configuration file exists in $SYSTEM.ZTCPIP, you must add two 
lines from the sample PROTOCOL file (SMPLPROT). Find the lines in SMPLPROT 
from the SUT that refer to IPV6 and ICMPV6 and copy those lines into your 
$SYSTEM.ZTCPIP.PROTOCOL file. For example:
12> TYPE SMPLPROT
#
# @(#)protocols 1.1 Tandem
#
# Internet (IP) protocols
# This file is never consulted when the yellow pages are running
#
ip   0    IP  # internet protocol, pseudo protocol 
number
icmp  1   ICMP  # internet control message protocol
ggp  3   GGP  # gateway-gateway protocol
tcp  6   TCP  # transmission control protocol
pup  12  PUP  # PARC universal packet protocol
udp    17   UDP  # user datagram protocol
ipv6   41   IP  # internet protocol for v6
icmpv6  58  ICMP # internet control message protocol for v6
Step 3: Ensure That PORTCONF and SERVICES Files Are 
Complete
The PORTCONF file specifies the ports that the LISTNER process listens to and the 
corresponding server program it invokes when the request comes in.
If you copied files as documented in Step 1, for the DSM/SCM Planner Interface to 
work, you must add a services line corresponding to DSM/SCM in the PORTCONF file 
(shown in bold lettering) and save the file. If you did not copy the files as documented 
in Step 1, no action is necessary. An example of the PORTCONF file:
58> type portconf
#
# This file tells the listner program which ports to
# listen to, and what programs to run
# Telnet is directly, and does not use the listner's
# services.
# To run the listner use:
# $system.ztcpip.listner / name.../ [config-file-name]
# where config-file-name is this file.
#
ftp $system.ztcpip.ftpserv
finger $system.ztcpip.fingserv
7 $system.ztcpip.echoserv
phiwsock $tdsv.zdsmscm.pdpexe
Caution. Even if you are running TCP/IPv6 in IPv4 or conventional TCP/IP mode, you must 
check that the PROTOCOL file contains ipv6 and icmpv6 entries. If these entries are absent, a 
network failure might occur because the new socket routines present in TELSERV, LISTNER, 
and FTP access the entries in the PROTOCOL file.
